998b7b1db4 make: fix where dependency *.d are stored.
In rules like "bar/%.o: %.c" there is a difference between $(*D) and
$(@D). $(*D) expands to '.', while $(@D) expands to 'bar'.  It is
cleaner to generate *.d in the same directory where appropriate *.o
resides. This allows precise including of dependency info from .d files.

As a hack, we also touch two sources for generated *.hex files.  Without
this hack, anyone doing "git pull; make" will not get *.hex rebuilt
correctly since the dependency file would be missing.

e94867ed5f block: don't register quorum driver if SHA256 support is unavailable
Commit 488981a4 [block: convert quorum blockdrv to use crypto APIs]
broke qemu-iotest 041 on hosts with GnuTLS < 2.10.0. It converted a
compile-time check to a run-time check at device open time. The result
is that we now advertise a feature (the quorum block driver) that will
never work (on those hosts). There's no way (short of parsing
human-readable error messages) for qemu-iotests or any other API
consumer to recognise that the quorum block driver isn't _actually_
available and shouldn't be used or tested.

Move the run-time check to bdrv_quorum_init() to avoid registering the
quorum block driver if we know it cannot work. This way API consumers
can recognise it's unavailable.

74aae7b22b virtio: fix 1.0 virtqueue migration
1.0 does not requires physically-contiguous pages layout for a
virtqueue. So we could not infer avail and used from desc. This means
we need to migrate vring.avail and vring.used when host support virtio
1.0. This fixes malfunction of virtio 1.0 device after migration.

The checks in dins is required to avoid triggering an assertion

In this case the errant dins appears to be data, not code, as

8c6dc68f4c migration: Fix regression for xenfv and pc,accel=xen machine.
This fix migration from the same QEMU version and from previous QEMU
version.

>From the global state section, we don't need runstate with Xen. Right now,
the way the Xen toolstack knows when QEMU is ready is when QEMU reach
"running" runstate.

The configuration section and the section footers are not going to be
present in previous version of QEMU with xenfv machine, so we skip them.

The Xen toolstack libxenlight does not specify a particular version of the
'pc' machine, so migration from older version of QEMU used by Xen to newer
one would break due to missing "configuration" section and section footers.

c69adea462 migration: Fix global state with Xen.
When doing migration via the QMP command xen_save_devices_state, the
current runstate is not store into the global state section. Also the
current runstate is not the one we want on the receiver side.

During migration, the Xen toolstack paused QEMU before save the devices
state. Also, the toolstack expect QEMU to autostart when the migration is
finished.
So this patch store "running" as it's current runstate.

IP header is present.  When we reach the if (ip) {...} statement we know
ip is always non-NULL.

Remove the if statement to reduce nesting.

39b8e7dcaf rtl8139: avoid nested ifs in IP header parsing (CVE-2015-5165)
Transmit offload needs to parse packet headers.  If header fields have
unexpected values the offload processing is skipped.

The code currently uses nested ifs because there is relatively little
input validation.  The next patches will add missing input validation
and a goto label is more appropriate to avoid deep if statement nesting.

c99d69694a tcg/mips: fix add2
The add2 code in the tcg_out_addsub2 function doesn't take into account
the case where rl == al == bl. In that case we can't compute the carry
after the addition. As it corresponds to a multiplication by 2, the
carry bit is the bit 31.

While this is a corner case, this prevents x86-64 guests to boot on a
MIPS host.

ca96ac44dc AioContext: force event loop iteration using BH
The notify_me optimization introduced in commit eabc977973
("AioContext: fix broken ctx->dispatching optimization") skips
event_notifier_set() calls when the event loop thread is not blocked in
ppoll(2).

This optimization causes a deadlock if two aio_context_acquire() calls
race.  notify_me = 0 during the race so the winning thread can enter
ppoll(2) unaware that the other thread is waiting its turn to acquire
the AioContext.

This patch forces ppoll(2) to return by scheduling a BH instead of
calling aio_notify().

The following deadlock with virtio-blk dataplane is fixed:

  qemu ... -object iothread,id=iothread0 \
           -drive if=none,id=drive0,file=test.img,... \
           -device virtio-blk-pci,iothread=iothread0,drive=drive0

This command-line results in a hang early on without this patch.

Thanks to Paolo Bonzini <pbonzini@redhat.com> for investigating this bug
with me.

7bba83bf80 xen: Drop net_rx_ok
Let net_rx_packet() (which checks the same conditions) drops the packet
if the device is not ready. Drop net_xen_info.can_receive and update the
return value for the buffer full case.

We rely on the qemu_flush_queued_packets() in net_event() to wake up
the peer when the buffer becomes available again.

ff1d2ac949 hw/net: handle flow control in mcf_fec driver receiver
The network mcf_fec driver emulated receive side method is not dealing
with network queue flow control properly.

Modify the receive side to check if we have enough space in the
descriptors to store the current packet. If not we process none of it
and return 0. When the guest frees up some buffers through its descriptors
we signal the qemu net layer to send more packets.

[Fixed coding style: 4-space indent and curly braces on if statement.

Replace memory_region_init_rom_device() with memory_region_init_ram() and
memory_region_set_readonly().
This fixes a guest-triggerable QEMU crash when guest tries to write to PROM.

30dfa9a46c net/dp8393x: remove check of runt packets
Ethernet requires that messages are at least 64 bytes on the wire. This
limitation does not exist on emulation (no wire message), so remove the
check. Netcard is now able to receive small network packets.
